Abstract

Disclosed is an electric shock prevention socket which belongs to articles for daily life. The utility model relates to an improvement of a socket structure, in particular to an electric shock prevention socket which can prevent electric shock accidents. The electric shock prevention socket with simple structure comprises a socket and a strong magnetic sheet arranged at the top end of a plug, anda dry reed tube corresponding to the strong magnetic sheet at the top end of the plug is arranged inside the socket. One line of a power source of 220V alternating current is connected with an input end of a rectifier bridge through a resistance-capacitance voltage reduction circuit, the other line is in series connection with a contact point of a relay and an output end of the socket, and an output end of the rectifier bridge is in series connection with the dry reed tube and a coil of the relay.

Description

A kind of anti-electric shock socket

Technical field:

The utility model belongs to daily living article, relates to the improvement of socket, relates in particular to a kind of anti-electric shock socket that prevents that electric shock accidents from taking place.

Background technology:

Socket is a requisite daily necessities in people's daily life; Yet existing socket does not have the electrocution-proof protection function, easily causes electric shock accidents; The family that children are especially arranged in the family, easier generation electric shock accidents causes damage for people's life, property.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of anti-electric shock socket simple in structure is provided.

For achieving the above object, the utility model adopts following technical scheme, the utility model comprises socket, is arranged on the strong magnetic piece on plug top, in socket, be provided with and the corresponding tongue tube of plug top strong magnetic piece, 220V alternating-current power supply one tunnel links to each other with the input of rectifier bridge through the resistance-capacitance depressurization circuit, the contact of another road and relay, the output of socket are connected in series, and the coil of the output of rectifier bridge and tongue tube, relay is connected in series.

The beneficial effects of the utility model:

Because the utility model comprises socket, is arranged on the strong magnetic piece on plug top, in socket, be provided with and the corresponding tongue tube of plug top strong magnetic piece, 220V alternating-current power supply one tunnel links to each other with the input of rectifier bridge through the resistance-capacitance depressurization circuit, the contact of another road and relay, the output of socket are connected in series, and the coil of the output of rectifier bridge and tongue tube, relay is connected in series; Just make socket of the present utility model when not having plug to insert, do not have electric current to pass through, the generation of electric shock accidents has effectively been avoided in no-voltage output, uses safety, reliable; And the utility model is simple in structure, is easy to make, and is easy to popularize.

Description of drawings:

Fig. 1 is a schematic block circuit diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment:

220V alternating-current power supply one tunnel links to each other with the input of rectifier bridge through the resistance-capacitance depressurization circuit that resistance R 2, capacitor C 1 are formed in parallel, the contact K1 of another road and relay J 1, the output of socket are connected in series, an output of rectifier bridge links to each other through the negative pole of resistance R 3 with capacitor C 2, another output links to each other with the positive pole of capacitor C 2, and capacitor C 2 two ends are parallel with the series arm of being made up of the coil of tongue tube K2 and relay J 1.Wherein, R1:120k; R2:680k; R3:5 Ω; C1:680 μ F400V; C2:47 μ F50V.

During use, earlier strong magnetic piece is installed in the top of power consumption equipment plug.When plug insertion socket, under the effect of plug top strong magnetic piece, tongue tube K2 conducting, relay J 1 gets electric, contact K1 adhesive; At this moment, the output of socket has voltage output, power consumption equipment operate as normal.When plug was extracted socket, tongue tube K2 disconnected, relay J 1 dead electricity, and contact K1 disconnects, and the output no-voltage of socket is exported, thereby has effectively avoided the generation of electric shock accidents.

Claims
